Peru Weather in September

The end of September officially marks the start of the spring season in Peru, and the weather is dry and pleasant in most parts during this time of year. However, it varies between regions, which means that you can find different weather conditions as you travel around.
Northern Peru is typically sunny and warm. Coastal cities like Mancora and Las Pocitas have ideal weather conditions for a beach getaway. The average daily temperature in the Mancora district is 26°C, while the ocean around the area remains cool, with the water temperature hovering between 16°C and 20°C.
The south, on the other hand, is colder. Lima experiences mild weather with the mercury hovering between 15°C to 19°C. If you head toward Lima’s south, you will find that the coastal areas are relatively empty, as foggy conditions are likely to disrupt beach activities in this region.
It is warm and sunny during the daytime in the Andean region. But be prepared for cold nights. Towns like Cusco average around 21°C during the day, but temperatures can plummet to 4°C after sundown. The Amazon is the warmest part of the country, with the highs of 32°C on the hottest day in September.
